25 Claims.

This invention relates to door locks and more particularly bore type locks, which are so-called because the transverse holes in the door made to receive the lock can be bored with an auger bit and there is very little mortising necessary.

One of the principal objects of my invention is to provide a lock of the kind mentioned which is quickly and easily convertible to suit right or left hand use and to change from a spring latch to a dead bolt, to suit requirements.

A salient feature of the lock of my invention consists in the provision of a detachable bracket carrying the operating finger arranged to be applied to the inner end of the bolt housing on either side, depending upon what side of the door is the outer side onto which the barrel oi the lock is to be applied, the bolt housing itself being rotatable about its longitudinal axis, and the aforesaid bracket being applicable thereto from the top or bottom, whereby to adapt the lock to a right or left hand door.

Another important object of my invention is to provide a. lock in which the bolt has a cam plate attached thereto with a pin and slot connection and operable by the aforesaid operating finger to move the bolt in either direction, the bolt housing carrying a spring pressed catch, which engages in notches in the bolt to hold it positively in either extreme position, the catch being arranged to be cammed out of the way by the aforesaid plate upon movement of the operating finger, thus providing a lock in which the bolt is tamper-proof, being securely held extended or retracted, although movable with the operating finger very smoothly and easily in either direction. Removal of the spring pressed catch and insertion of a spring to hold the bolt normally extended are the only things which it is necessary to do to convert the dead bolt to a spring latch.

The invention is illustrated in the accompanying drawing, in which- Figure 1 is a view looking at the free edge of a door equipped with a lock made in accordance with my invention, a portion of the door and lock being shown in section to better illustrate the invention;

Fig. 2 is a side View of the bolt housing removed from the door and showing the bracket and operating finger assembly mounted thereon;

Fig. 3 is an inside view of the bolt housing, the removable housing side plate having been removed;

Figs. 3a and, 3b correspond to a portion of Fig. 3, but show the parts in moved positions to 2 illustrate the camming out of the way of the catch in the movement of the bolt in both directions;

Fig. 4 is a cross-section on the line 4-4 of Fig. 2, indicating in dotted lines one of three other possible positions of assembling the detachable bracket and operating finger assembly, and

Fig. 5 is a view similar to Fig. 3 with the catch removed and a spring inserted to convert the dead bolt of Fig. 3 to a spring latch.

The same reference numerals are applied to corresponding parts throughout the views.

Referring to Fig. 1, the reference numeral 6 designates a door in which the transverse holes 1 and 8 are bored with auger bits to receive the lock of my invention, designated generally by the reference numeral}. I0 is the bolt reciprocable in the generally cylindrical housing ll received in the hole I and fastened in place in the usual way by the escutcheon plate l2 in a recess i3 .mortised in the edge of the door. A side plate l4 forming substantially half of the housing II is removably secured in place by a screw 15 threading in a hole in the neck l6 provided inside the housing. The bolt 10 is guided for reciprocation in the housing H in the bearings l1 and I8 and has a lost motion connection with an elongated cam plate [9 by means of pin projections 20 on the bolt slidable in slots 2| in the plate. There are two cam surfaces 22 and 23 on the lower edge of the plate IS in longitudina'lly spaced relation. These cam surfaces are for actuating a catch 24 that is pivoted on the neck l6 and has 3, lug 25 projecting laterally from the free end thereof for engagement in either one of two longitudinally spaced notches 26 and 21 provided in the bottom of the bolt ID. A coiled compression spring 28 seated at one end in the housing and having its other end fitted over a lug 29 projecting downwardly from the catch 24 serves to urge the catch normally into engagement with the bolt.

In operation, the bolt ll! can be moved in either direction by'means of the cam plate l9. In retracting the bolt from the extended position shown in Fig. 3, the: cam surface 23 in the initial movement of the plate I9 releases the catch 24, as shown in Fig. 3a, and then the bolt is, of course, free to moveir'iwardly relative to the housing H. At the end of the inward movement, the lug 25 on the catch 24 engages in the notch 21, thus locking the bolt positively in retracted position. Thereafter when the bolt is to be extended, the initial outward movement of the cam plate l9 causes release of-the catch 24 by cooperation of the cam surfac 22 with the lug 25 in th manner shown in Fig. 3b. After release of the catch 24, th bolt ID is of course free to move with the plate l9, similarly as in retracting the bolt. The operation is smooth and easy both Ways, and it should be clear that the catch locks the bolt positivelyin either extreme position and the bolt is therefore tamper-proof.

The bolt I!) has a tubular guide portion 30 extending inwardly therefrom and having a free telescoping fit on a pin 3| mounted in the housing II and extending longitudinally thereof. When it is desired to convert the dead bolt shown in Fig. 3 to a spring latch, as shown in Fig. 5, the only changes necessary are the removal of the catch 24 with its spring 28 and the provision of a long coiled compression spring 32 in the housing acting between the housing and bolt, as shown in Fig. 5. The guide 30 forms a convenient mounting for the spring 32. In operation, this spring latch permits slamming the door with'the bolt projecting, but, of course, it requires the operation of the inside knob 33, or the key 34 on the outside of the door, as will soon appear, to retract the bolt so that the door can be opened.

The bolt housing fits freely in the hole 1 bored in the door 6 and is adapted to be turned through 180 to hav the beveled face 35 on the outer end of the bolt l face one way for right hand operation, as it appears in Fig. 1, and in the opposite direction for left hand operation. The operating finger 36 is pivotally mounted by means of a bushing 31 on a bracket 38 arranged to be detachably mounted on the bolt housing II in either one of two bearings 39 and 40 provided on opposite sides thereof. The bearing 4|! is formed as a part of the side plate l4. The bracket 38 can be mounted in either of these hearings from either end, thereby enabling the assembling of the operating finger 36 with its forked end 4| straddling the cross-pin 42 on the inner end of the cam plate l9 in either one of four positions to suit either a right or left hand door, .and in either of those instances the placihg, ofthe cylinder lock 43 on the inner or outer side of the door. The inner end of the housing ll has a diametrically extending opening 44 to permit entry of the finger 36 from either side for connection of the fork 4| with the pin 42. The'bracket 38 will, of course, be assembled on the housing I after the latter has been entered in the hole 1. That can be done easily through the larger transverse hole 8, as should b apparent from inspection of Fig. 1, the housing having its inner end projecting into the hole 8 to the extent indicated for easy entry of the operating finger 36 down into the opening 44 to connect with the pin 42 at the same time that the'brack'et 38 is entered in th bearing 39 or 40 as the case may be. It is manifest, therefore, thatto install this look the carpenter can quickly and easily adapt it to the specific requirements of the job in hand, because the lock is universally adaptable. There is no need for the supply house handed locks in stock. Consequently there is a saving in cost' and the likelihood of confusion'and delays is avoided.

The cylinder lock, indicated at 43, is of conventional design and construction and is adapted to be entered in one end of the hole 8 after an escutcheon'ring 45 has been pressed'or driven into that 'end of the'hole. The lock is secured in place from the opposite side of the door by an a and the axis of the cylinder may be at a slight escutcheon plate 46 through which two screws,

one of which is indicated at 47 in Fig. 1, are exclearly appears in Fig. 1, the shank portion of.

the knob 33 is rotatably mounted in the escutcheon plate 48. Now, the shaft 52 is connected intermediate its ends with the operating finger 35 by entry through the square hole 54 in the bushing 31, whereby to oscillate the operating finger i the turning of the shaft by means of the knob 33 or key 34. The lost motion at 5| permits 99 turning of the shaft 52 independently of the cylinder 55 as required in unlocking the door from the inner side. There is sufiicient play also at the connection 5| so that the knob 33 does not have to be exactly aligned with the cylinder 50 angle to the axis of the knob. In that way the lock will operate smoothly and easily and there will be no tendency to bind, even if there is a certain amount of misalignment. The fact that the operating finger 36 has its operated end 55 in offset parallel relation to the forked end 4| to the extent shown in Figs. 1 and 4, the supporting bracket 38 having its outer end 56 likewise offset from its supported end 51, enables the close coupled relationship illustrated between the lock 43 and bolt housing II, and in that way the lock 43 can be placed substantially flush with the outside of the door, leaving little or nothing exposed on which a burglar can work in attempting to break in. In many other locks with which I am familiar, th escutcheon plate on the outside of the door had to be of an embossed design approximately to the extent of the offset of the portion 55 with respect to the portion 4| of the operating finger 36. Such an embossed esv cutcheon plate invites tampering. The ofiset in the bracket 38 is incidentally of advantage in providing the intermediate bearing portion 58, which, as indicated in Fig. l, is adapted to rest on the lower side of the hole 8 to help support the bracket and tend to eliminate side thrust on the shaft 52 by reason of the more definite location of the bushing 31 in relation to the hole ,8 into which the lock 43 is entered.
